the uidNumber attribute of the posixAccount objectClass is single 
valued; i.e. u cannot add more than one attribute of uidNumber to a dn 
that has a posixAccount. So the only solution I think to guarantee the 
uniqueness of ur customers' uidNumber is on ur client side.
1 - search for this uidNumber in ur tree
2 - if found then do not add
3 - if not found then add
I hope this helps
